	The '''IBM PS/2 Model 65 SX Supplement for the Hardware Interface and BIOS Interface Technical References''', dated ~~'''~~6 March 1990~~'''~~, ~~'''~~part number 15F2174, form number S15F-2174-00~~'''~~. 72 pages.		The '''IBM PS/2 Model 65 SX Supplement for the Hardware Interface and BIOS Interface Technical References''' is an IBM update package dated 6 March 1990, part number 15F2174, form number S15F-2174-00. The hosted scan is 72 pages and image-only; the last few pages are blank.

	~~== What~~ it ~~contains ==~~		The instruction page (PDF page 2) says to insert a "Model 65 SX" tab in front of the "Model 70" tab of the ''Hardware Interface Technical Reference'' with the ''IBM Personal System/2 Model 65 SX Technical Reference'' pages behind it, and to file the "IBM Personal System/2 Model 65 SX Supplement" page behind the Supplements tab of the ''PS/2 and PC BIOS Interface Technical Reference''.

	~~IBM's~~ filing instructions and ~~the pages they refer~~ to:		== Contents ==
			* PDF page 1: cover. Page 2: filing instructions. Page 3: tab separator ("Insert the hard tab labeled 'Model 65 SX' here, then discard this page").
			* From PDF page 6: the ''Model 65 SX Technical Reference'', First Edition (March 1990), with its edition notice, preface, sections 1 to 3 and index (to about PDF page 64).
			* PDF page 66: the BIOS supplement page, a table of the model and submodel bytes for the Model 65 SX.

	~~# Insert~~ the ~~tab labelled "Model 65 SX" '''in front of~~ the ~~"Model 70" tab''' of the ''Hardware Interface Technical Reference'', and file the ''~~IBM ~~Personal System/2~~ Model 65 SX Technical Reference~~'' pages behind it.~~		== What this document does not contain ==
	~~# File the ''Model 65 SX Supplement'' page behind the Supplements tab in the ''BIOS Interface Technical Reference''~~.		There are no FRU numbers, removal procedures, schematics or component values. The technical reference inside is the first edition; the [[IBM PS2 Model 65 SX Technical Reference (October 1990)\|October 1990 second edition]] adds a power supply section and marks its changes with vertical bars.

	~~The Model 65 SX technical reference pages follow — the same material published bound~~ as ~~the~~ [[IBM PS2 Model 65 SX Technical Reference (October 1990)~~\|October 1990 technical reference~~]], ~~seven months earlier.~~		== Pages that cite this document ==
			* [[IBM PS2 Hardware Interface Technical Reference (May 1988)]] lists it as a supplement filed into that binder.
	~~== What it does not contain ==~~		* [[IBM PS2 Model 65 SX Technical Reference (October 1990)]], [[IBM PS2 Model 55SX HITR Supplement]] and [[IBM PS2 Model P70 HITR Supplement]] list it as related.

	~~'''No text layer''' — an image-only scan.~~

	~~This is a '''loose-leaf update package, not a book'''. It has no contents page, no index~~ and ~~no standalone narrative: the first pages are~~ IBM~~'s filing instructions, followed by hard-tab separator sheets that say "Insert the hard tab labeled ... here, then discard this page", followed by the replacement pages themselves. Read~~ it ~~knowing that structure, or the first few pages look like a scanning error.~~

	~~It contains no FRU numbers, no removal procedures, no component values and no schematics~~.
